EST (1 1/4"-10") |
Electronic Solenoid Timer for monitoring relief valve discharge (See web link for description) |
||||||
|
The EST control box operates on a 120VAC power source and monitors the switch in the backflow relief valve. When the EST registers a relief valve dump, the system will shut down the ZW106 control valve which basically turns the system off, and sends a signal to the EST control box. The EST can be programmed to: |
|||||||
|
● Trigger local alarms, warning lights, sirens or buzzers |
|||||||
|
● Trigger a central alarm system |
|||||||
|
● Call maintenance personnel |
|||||||
|
● Switch a relay to start a sump pump |
|||||||
|
● Or any other response that can be accomplished with a signal from the EST |
|||||||
|
The EST works with a 375 or 975 RP backflow preventer, relief valve monitoring switch, and a ZW106 Solenoid Control Valve. Package pricing is as follows: |
